Question about the existence of the normalization, and how to run it

[hyunW3]

I'm impressed with your work.

1. About normalization
   I wonder if the l2 normalization of embeddings of pixel i $i \in I$ and prototypes $p_{c,k}$ exists in your code. If exists, I'm glad to get the answer of where it is. The below image is from the your paper.
   

2. how to run it

• Basically, i check README.md but i cannot find how to run it. Simply running main.py requires some config path like

TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType

It might need the config files to set the config. Could you let me know the basic running code?

3. The difference b/w main.py and main_contrastive.py
   What is difference b/w them?

Thank you for reading
